There’s so many pre ww2 players I’d want to see added, but I’ll name just a few of the more interesting ones:
Grover Cleveland Alexander, one of the best pitchers of all time, would have a 99 sig SP as well as a 85+ reliever card for his work in the 1926 World Series.
Bob Muesel was a forgotten member of the 1920s Yankees who was just as fearsome a hitter as anybody in the league except Ruth. He would likely be a 95-97 overall.
Dazzy Vance didn’t break out until he was 31 - but then proceeded to dominate the National League during the most prolific hitting era ever. He would be a 96-98 SP with outlier.
Smoky Joe Wood had a good pitching career before arm injuries derailed him. He decided to become an outfielder, and he had a decent end to his career. He would have two cards again, and his signature pitcher card would be a pitcher who rakes.
Finally there’s all of the negro league players that have been mentioned in a ton of other threads. Satchel Paige, Josh Gibson, Cool Papa Bell, Buck Leonard, and every single legend. Those would be the coolest.
